I need to check the file attachment size on the form on submit

[Barnali Rakshit]

Need to write a Client Script where the attachment file should not be bigger than 5 MB , after uploading the file , when click on Submit it should throw an alert message and user should not be able to submit the request before uploading the right size file.

Hi 

I have tried the below code but it is not working

function onSubmit() {
   //Type appropriate comment here, and begin script below
    var sys_id = g_form.getUniqueValue();
    var gr = new GlideRecord('sys_attachment');
    
    //gr.addQuery("table_sys_id", cat_id);
    gr.addQuery('table_sys_id',sys_id );
    gr.Query();
    
    var totalSize=0;
    while(gr.next()) {
    
        
        totalSize = parseInt(gr.size_bytes);
        totalSize=(totalSize / Math.pow(1024, 2)).toFixed(2) * 1;
    
    
    if(totalSize > 5) {
    alert("Attachment size exceeded");
        
        return false;
    }
    }
    
}

Hi, Add the below variable attribute for the attachment variable:

max_file_size=5

here 5 denotes 5 MB, you can change number as per your requirement.

Thanks,
